Although most of the cases that have been documented so far show that this variant causes mild symptoms of covid-19. However, the World Health Organization has been clear in pointing out that it is not yet known how serious Omicron is.

In the United States, when they register just over four dozen cases of the Omicron variant, the authorities highlight the following data:

  • 58% correspond to people between 18 and 39 years old.
  • November 15 is the earliest date of appearance of symptoms related to this variant, in a person with a history of traveling abroad
  • 33% of the cases reported having traveled abroad at least 14 days before the onset of symptoms or a positive result.
